PEDESTAL-BASE FOR BARBER-CHAIRS.

Application filed March 31, 1919.

To all whom t may concern;

Be it known that I, WALTER F. KOKEN, a citizen of the United States, residing at St. Louis, Missouri, have invented a certain new and useful Improvement in Pedestal- Bases for Barber-Chairs, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to chairs ofv the kind that are used by barbers, dentists and other specialists, and particularly to barber chairs of the type which are provided with a pedestal base formed of metal.

The type of metal base that is now universally used on barber chairs consists of a hollow casting comprising a base portion and a pedestal portion integrally connected together and means on the base portion of the casting for sustaining the socket member' of the chair that receives the stem which carries the seat frame. A cast metal pedestal base of the kind referred to is very heavy, thus making the chair cumbersome to handle and expensive to ship from the manufacturer to the user, and such a base is costly to manufacture on account of the necessity of grinding oft' the outer surface of the casting when the base is finished in porcelain enamel. Unless considerable skill and care are used in grinding off the outer surface of the casting preparatory to enameling it, the finished base will have a wavy or irregular outer surface. If the chair manufacturer is not equipped with a large oven and is obliged to send the pedestal base casting to another city to be enameled, the cost of transporting the casting is a large item in the complete cost of manufacturing the chair, due to the excessive weight of the casting.

The obj ect of my invention is to provide a pedestal base for barber chairs, dentist chairs and the like; that is light in weight and inexpensive to manufacture.

To this end I have devised a pedestal base for barber chairs andthe like whose exterior or outer surface is formed by a sheet metal shell, thereby producing a chair base that is light in weight; that can be manufactured cheaply in a die press and which can be finished in porcelain enamel without first grinding oftl the surface that is to be coated with enamel.

Figure l of the drawings is a vertical sectional view of a chair base constructed in accordance with my invention.

Fig. 2 is a vertical sectional view, illustrating another form of my invention; and

Fig. 3 is a perspective view of one of the clips used to connect the rim of the base portion to the base casting of the supporting structure,

Referring to Fig. l of the drawings, which illustrates one form of my invention, A7 B and C designate three sheet metal members that cooperate with each other to form a shell comprising a substantially fiat base portion and a vertically-disposed pedestal portion whose lower end flares outwardly and merges into said base portion.

The member A is of tubular form, the member C is fiat or of substantially plate form and the intermediate member B is of substantially frusto-conical-shape in general outline. A cap piece D is mounted on the upper end of the tubular member A, and a base rim E is combined with the horizontally-disposed member C in such a manner that it gives a finished appearance to the peripheral edge of the base.

All of theV parts above. referred to are preferably formed from sheet metal and they are carried by a supporting structure composed of a base casting l that rests upon the floor and a socket member 2 that rests upon said base casting and projects upwardly from the center of same through the tubular member A of the pedestal portion of the shell, said socket member being adapted to receive the vertically-adjustable stem of the chair (not shown) that carries the seat frame. It is immaterial how the base casting l and the socket member 2 are formed and connected together, but one convenient way of combining said parts is to provide the base casting l with a center opening that receives the lower end portion of the socket member 2, said socket member being provided with a laterally-projecting flange 3 or lugs that rest upon the base casting l, as shown in the drawings. The horizontally-disposed sheet metal member C rests upon the base casting l and is provided at its peripheral edge with a depending flange or downwardly turned portion 4 that laps over the peripheral edge portion of said casting, and thus holds said member C in concentric relation with said casting.

connected together. In the form of my nvention shown in Fig. l the vmembers A, B and C are so constructed that one telescopes over the other, and the cap D and base rim E are used to clamp said members together and also clamp the horizontallydisposed 'member C to the base casting l of the supporting structure. When the members A, B and C are arranged in telescopic engagement with each other it is preferable to provide the horizontally-disposed member C with alarge centefopening whose edge portion is turned upwardly so as to form a rim or flange 5 over which the lower end of the intermediate member B telescopes, and provide the member B at its upperend with an upwardly-projecting rim or flange 6 that is arranged inside of the lower end of the tubular member A. The cap piece D is connected either to the socket member 2 or to the base casting l of the ,supporting structure in such a manner that it can be drawn downwardly so as to force the members A, B and C tightly together. In the form of my invention shown in Fig.

lthe cap piece D is connected by means of screws 7 to laterally-projecting lugs 8 on the socket member 2, and in the form of my invention shown in Fig. 2 the cap piece D Yis retained in position and drawn downwardly into snug engagement with the upper edge of the tubular member A by means of long bolts 7a that pass downwardly through the cap piece and are screwed into the flange at the lower end of the socket member. The base rim E is so formed that it laps over the peripheral edge portion of the horizon-V tally-disposed member C of the shell, and said rim is connected to the base casting l preferably by means of clips 9 secured to a laterally-projecting flange or lugs 10 on the base casting l and arranged inside of the rim E, as shown in Fig. l, each of said clips being provided at its inner end with a downwardly turned portion 9a that bears upon the base casting and at its outer end with a downwardly turned portion 9b that bears on an inwardly-projecting flange ll on the rim E. When the screws l0 are tightenedjthe clips 9 will cause the rim E to be drawn downwardly, thereby securely clamping the member C of the shell tothe base casting l of the supporting structure.

Instead of forming the sheet metal shell from three members, as shown in Fig. 1, said shell can be formed by a tubular member A and a base member F provided with an integral, upwardly-projecting portion F that tapers inwardly and merges into the tubular member A. The portion Ff of the member F can either be arranged in telescopic engagement 'with the tubular member A, or said portion F can be permanently connected to the lower end of the member A by welding, the portion F being provided at its Lipper end with a part 6a on which the loweredge of the tubular member A rests.

A pedestal base of the construction above described is considerably lighter in weight than the metal pedestal bases heretofore used on barber chairs, owing to the fact that it is composed, principally, of sheet metal. Accordingly, such a pedestal base effects a considerable saving in the cost lof transporting the chair from the manufacturer to the user. Furthermore, such a pedestal base can be manufactured at a'low cost, as the sheet metal parts of same Vcan be formed in a die press and they can be finished in porcelain enamel without the necessity of firstfgrinding off the surface to be coatedy with enamel.

Having thus described my invention, what I claim and desire to secure by Letters Patent, is:

1. A pedestal base for chairs, comprising a supporting structure, a shell forming the exterior' of the pedestal base and comprising a base portion and a pedestal portion formed by-a plurality -of sheet metal members, a cap mounted on the upper endvof said pedestal portion, a rim surrounding said base portion, and means for securing said cap and rim to the supporting structure.

2. A pedestal base for chairs, comprising a base casting, a sheet metal shell Vforming the exterior of the pedestal base, and a base rim secured to said base casting and arranged so that it clamps a portion of said shell to said base casting.

3. A pedestal base for chairs composed of a base casting, a socket member mounted on said base casting, a sheet metal shell that forms the exterior ofthe pedestal base, and means connected to said base casting and socket member for retaining said shell in operative position.
